[LAU] JACK recovery

Hi, I'm doing some development work, so naturally (well, maybe it;s just me...) and occasionally I attempt to run my code before I've started JACK. After that it can not be started until I reboot, typical error: 09:59:57.411 Could not connect to JACK server as client. - Overall operation failed. - Unable to connect to server. Please check the messages window for more info. Cannot connect to server socket err = No such file or directory Cannot connect to server request channel jack server is not running or cannot be started JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for 4294967295, skipping unlock JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for 4294967295, skipping unlock My question is what SHOULD i be doing in my code to prevent this? (Obviously, I can start JACK in my code if it's not running...but, I've not found any info on checking for JACK and starting it from python. AND, how do, or can, I get JACK to start after this occurs without a reboot? Regards, Mac
